CVSS: 3.7EPSS: 0%CPEs: 16EXPL: 1CVE-2023-28322 – curl: more POST-after-PUT confusion
https://notcve.org/view.php?id=CVE-2023-28322
An information disclosure vulnerability exists in curl <v8.1.0 when doing HTTP(S) transfers, libcurl might erroneously use the read callback (`CURLOPT_READFUNCTION`) to ask for data to send, even when the `CURLOPT_POSTFIELDS` option has been set, if the same handle previously wasused to issue a `PUT` request which used that callback. This flaw may surprise the application and cause it to misbehave and either send off the wrong data or use memory after free or similar in the second transfer. The problem exists in the logic for a reused handle when it is (expected to be) changed from a PUT to a POST. A use-after-free flaw was found in the Curl package. This issue may lead to unintended information disclosure by the application. • http://seclists.org/fulldisclosure/2023/Jul/47 http://seclists.org/fulldisclosure/2023/Jul/48 http://seclists.org/fulldisclosure/2023/Jul/52 https://hackerone.com/reports/1954658 https://lists.debian.org/debian-lts-announce/2023/12/msg00015.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/F4I75RDGX5ULSSCBE5BF3P5I5SFO7ULQ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/Z2LIWHWKOVH24COGGBCVOWDXXIUPKOMK https://security.gentoo • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-440: Expected Behavior Violation •

https://notcve.org/view.php?id=CVE-2023-27537
A double free vulnerability exists in libcurl <8.0.0 when sharing HSTS data between separate "handles". This sharing was introduced without considerations for do this sharing across separate threads but there was no indication of this fact in the documentation. Due to missing mutexes or thread locks, two threads sharing the same HSTS data could end up doing a double-free or use-after-free. • https://hackerone.com/reports/1897203 https://security.gentoo.org/glsa/202310-12 https://security.netapp.com/advisory/ntap-20230420-0010 • CWE-415: Double Free •
CVSS: 8.8EPSS: 0%CPEs: 15EXPL: 1CVE-2023-27533 – curl: TELNET option IAC injection
https://notcve.org/view.php?id=CVE-2023-27533
A vulnerability in input validation exists in curl <8.0 during communication using the TELNET protocol may allow an attacker to pass on maliciously crafted user name and "telnet options" during server negotiation. The lack of proper input scrubbing allows an attacker to send content or perform option negotiation without the application's intent. This vulnerability could be exploited if an application allows user input, thereby enabling attackers to execute arbitrary code on the system. • https://hackerone.com/reports/1891474 https://lists.debian.org/debian-lts-announce/2023/04/msg00025.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/36NBD5YLJXXEDZLDGNFCERWRYJQ6LAQW https://security.gentoo.org/glsa/202310-12 https://security.netapp.com/advisory/ntap-20230420-0011 https://access.redhat.com/security/cve/CVE-2023-27533 https://bugzilla.redhat.com/show_bug.cgi?id=2179062 • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') CWE-75: Failure to Sanitize Special Elements into a Different Plane (Special Element Injection) •
CVSS: 5.5EPSS: 0%CPEs: 17EXPL: 1CVE-2023-27538 – curl: SSH connection too eager reuse still
https://notcve.org/view.php?id=CVE-2023-27538
An authentication bypass vulnerability exists in libcurl prior to v8.0.0 where it reuses a previously established SSH connection despite the fact that an SSH option was modified, which should have prevented reuse. libcurl maintains a pool of previously used connections to reuse them for subsequent transfers if the configurations match. However, two SSH settings were omitted from the configuration check, allowing them to match easily, potentially leading to the reuse of an inappropriate connection. • https://hackerone.com/reports/1898475 https://lists.debian.org/debian-lts-announce/2023/04/msg00025.html https://security.gentoo.org/glsa/202310-12 https://security.netapp.com/advisory/ntap-20230420-0010 https://access.redhat.com/security/cve/CVE-2023-27538 https://bugzilla.redhat.com/show_bug.cgi?id=2179103 • CWE-287: Improper Authentication CWE-305: Authentication Bypass by Primary Weakness •
CVSS: 9.1EPSS: 0%CPEs: 14EXPL: 1CVE-2023-23914 – curl: HSTS ignored on multiple requests
https://notcve.org/view.php?id=CVE-2023-23914
A cleartext transmission of sensitive information vulnerability exists in curl <v7.88.0 that could cause HSTS functionality fail when multiple URLs are requested serially. Using its HSTS support, curl can be instructed to use HTTPS instead of usingan insecure clear-text HTTP step even when HTTP is provided in the URL. ThisHSTS mechanism would however surprisingly be ignored by subsequent transferswhen done on the same command line because the state would not be properlycarried on. A flaw was found in the Curl package, where the HSTS mechanism would be ignored by subsequent transfers when done on the same command line because the state would not be properly carried. This issue may result in limited confidentiality and integrity. • https://hackerone.com/reports/1813864 https://security.gentoo.org/glsa/202310-12 https://security.netapp.com/advisory/ntap-20230309-0006 https://access.redhat.com/security/cve/CVE-2023-23914 https://bugzilla.redhat.com/show_bug.cgi?id=2167797 • CWE-319: Cleartext Transmission of Sensitive Information •
